Good post Dan, this is precisely why i dont post in these type of threads. Without knowing in extensive detail about every factor its just that a guessing game and doesn't help the OP. Take it to an engineer and get a full report with every engine part inspected. The oil control opinion you also have is something i firmly agree with, we are definately on the same page Dan.
Its like those "my cars running rough threads" when everything from AFM's, coil packs, to tail light bulb blown is mentioned.
